Lets continue here 
Seems like a npm path issue but not sure yet - possibly caused by the env variable as described here node.js - NPM: npm-cli.js not found when running npm - Stack Overflow
Full scope of my error.
I installed the latest version of nodejs 18.10.0, npm v8.19.2, but it seems Unity has another version preinstalled because it keeps saying my npm version is deprecated.
I have two projects opened with two path set-up:
**Method 1. **
I clicked on “Run Needle Project Setup” so Needle finds the npm verison itself - this is not working
Errors -
npm ERR!, npm WARN deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.)
npm WARN deprecated mkdirp@0.5.1: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
**Method 2. **
From project settings, I selected my local files as my new npm verisons - this shows play, loads the local host page, but breaks.
Error
npm ERR!
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See There’s Math.random(), and then there’s Math.random() · V8 for details.
Installation did not succeed.

Mkdir fails? Can you try downgrading to node 16 (LTS)?
Ok. I’m going to try. Thank You.
by user 558970653626073099
With node 16 i don’t get errors but it doesn’t seem to work either:

And nothing changes here:

by user 558970653626073099
Can you go to Edit/ProjectSettings/Needle and send a screenshot of the settings?
Can you try deleting the paths in the fields and running the setup again?
Unfortunately nothing changed.
by user 558970653626073099
It writes back the paths, but not much else.
